Hi Adam, you are right in principle, even for cPanel & WHM to run on properly, SELinux must remain disabled.
SELinux it's useful to enforce the security of the server, and I was happy when I saw that CWP PRO has support for it.
From what I read around the forums, always errors had appeared between SELinux and Dovecot or Postfix.
Official SELinux support says that it's designed to work well with Dovecot but in custom configurations as on control panels there are always big chances to appear some errors.
Since it was included directly in the CWP PRO, it meant that it was also compatible rules in place to run without hassle.
But seems that after last updates, and SELinux updates too some issues appeared.
Unfortunately, I do not have the necessary knowledge to develop this set of rules, which is why I made this topic, maybe several heads will find a viable solution.
